Camera for biological applications
Jurák, Petr ; Slovák, Jiří (referee) ; Kubíček, Michal (advisor)
This diploma thesis is focused on the design of IP blocks for thermal camera. This termal camera is intended for plant research. The main part of the thermal camera is an infrared detector that detects a frequency in the range of 8 – 14 m. The analogue signal obtained is modified and subsequently digitized. The detector also includes a Peltier device which is designed for both detector cooling and heating, and is controlled by an external signal. The MicroZed development board implements IP blocks. The thermal camera is designed to be controlled from the MicroZed board. Device analysis is first described from the theoretical part to the design of IP blocks.

Analysis of infrared acquisition parameters
Zembol, Filip ; Drastich, Aleš (referee) ; Čech, Petr (advisor)
The topic of my thesis is the analysis of parameters of the infrared imaging and the use of radiation laws for the formation of a thermographic equation, which will include the impact of surrounding factors on the resulting temperature relief of the scanned object. These factors include the temperature of the surrounding atmosphere, temperature of the surrounding radiation sources, emissivity coefficients, reflection and transmission. On the basis of this equation a programme will be created in the MATLAB environment where the resulting temperature relief of the simulated object and the impact of the particular parameters from the equation will be graphically depicted. In the thesis we will first of all introduce the infrared radiation, its types and features. With the help of the particular radiation laws and distracting elements of the infrared radiation a formula including the distracting elements appearing during scanning of the thermal surface relief will be formed. This formula will enable us to count the surface temperature of the scanned scene and to determine the final temperature without the impact of the unwanted parameters. Furthermore, a programme which will image thermograms on the basis of the thermography equation will be designed. The thermogram will change in dependance on the changes of the parameters in the thermography equation. The change will be expressed by the change of temperatures in the scanned scene and by the shift in the colour spectrum (thermographic scale). This programme will graphically present the changes of the quantities influencing the resulting temperature division in the scene and will provide a better grasp of the influence and the function of particular quantities in the thermographic equation.

Magic Projection
Kaisler, Vojtěch ; Polok, Lukáš (referee) ; Zachariáš, Michal (advisor)
The bachelor thesis describes the design and implementation of an application which projects an image on a mobile canvas. The user then moves the canvas within the projection space. The projection is always focused only on this canvas. The thesis deals with tracking of movement, rotation and tilt of the screen. A camera with an infrared filter is used for tracking the canvas fitted with infrared LEDs. The thesis mentions two different types of projection.

FITkit as a Remote Controller Transceiver
Růžek, Michal ; Strnadel, Josef (referee) ; Vašíček, Zdeněk (advisor)
The bachelor's thesis is about communication protocols used in infrared remote controls of consumer electronics. It describes widely used protocols such as RC5, NEC and SIRC, their properities and methods of decoding. Transceivers are realized via components inside FITkit's FPGA chip, using simple HW module. Demo application written in C language is also included.

Biometric System Performance Testing - Vein Technology
Pandoščák, Michal ; Drahanský, Martin (referee) ; Orság, Filip (advisor)
This thesis aims at performance testing of a biometric device based on a vein recognition technology. Basic principles of this technology are briefly described. PalmSecure device was tested to illustrate the principle of the vein pattern scanning. Preformance tests and tests to fool the device were carried out. Finally, based on all acquired information a prototype of a palm vein pattern scanner was designed.

Verification of thermal-insulation properties of the foil materials
Šot, Petr ; TROJAN,, Karel (referee) ; Šťastník, Stanislav (advisor)
The master´s thesis deals with verification of thermal insulating property of thermoreflection foil insulations. The teoretical part of thesis focuses on the energy demand of buildings, the problems of heat transfer material, terms required for study of thermoreflection thermal insulation and experimental methods for determination of thermal insulating properties of insulators. In the next part the chapter is accompanied by an overview of the most common insulation materials which used in construction. The last part of teoretical part is devoted to the description of thermoreflect formation and analysis of the spread of thermal insulating layers of thermoreflection thermal insulation. The first part of thesis is devoted to the use of thermoreflection therm insulation in buildings. The second part of thesis is devoted to the design, assembly and calibration of the measuring device that uses a method of protected warm chamber. It is declared as a binding method of detection of the heat transfer performance of thermoreflection thermal insulation. The developed measuring device allows detection of endpoints in some direction of propagation of heat. Measurment of heat transfer coefficient devoted the third part of practical part. This part contains a description of the samples used for the measurement of the heat transfer coefficient. In the fourth chapter of the practical part are presented the results of the heat transfer coefficient measurments on selected samples of thermoreflection foil insulation. It is shown the characteristic of heat transfer coefficient of individual samples, the dependence of the heat transfer coefficient on the position of the sample in the measuring device and the recommendation of an appropriate use of sample in the works for the climatic conditions of the Czech republic. The work concludes the chapter of comparing and evaluating of all samples with practical recommendations.
